Van Kleiss has found a way to enhance Breach's powers so she can now open portals in time. To stop this dangerous threat, Rex must attempt to lure her over to the good side.
While battling Breach, Rex tries to cure a giant Tyrannosaurus-looking EVO that Breach brings out of a golden portal, only to discover it is an actual Tyrannosaurus. In the confusion, Breach escapes and the Tyrannosaurus rapidly ages, turning to dust two hours later.
Back at Providence Headquarters, it is determined that Breach has developed time travel powers and represents an enormous threat to national security. In short, Breach needs to be brought in and Rex volunteers to do it. During the briefing Agent Six notices White Knight is acting strangely and convinces Dr. Holiday to look into it. Rex travels to Abysus where Breach is being experimented on by Van Kleiss, and convinces her to escape with him.
Breach does not trust Rex and proceeds to take him to various places to see if he can understand her. The Pack shows up trying to retrieve Breach, with Van Kleiss activating Breach's harness to prevent her from teleporting away. Rex discovers that while the harness is activated, he is unable to shut it down. Rex and Breach escape, and Rex tries to convince Breach to come with him to Providence.
His attempt is thwarted by the arrival of a Providence squad which begins attacking Breach. They are in turn attacked by The Pack. Rex activates Breach's harness, giving her the choice of how to use it. Breach sends Van Kleiss away through a time portal, and finds she cannot shut down the harness. She thanks Rex for being a friend, and both of them disappear through a time portal.
Rex awakes alone in the middle of a desert and calls Providence to come and pick him up. When he arrives back at Providence HQ, he discovers he has been missing for six months, Caesar has grown a goatee, all of his friends have left Providence, and a woman named Black Knight is now in charge.
- At one brief moment in Abysus, Van Kleiss' eyes are seen to be light green, like Breach's, and then revert back to their proper brown color.
